Nissan ECU Tuning

Hi,

I just installed a DOOLZ intake setup and found the K-Value on my aftermarket chip. I changed it from 00 d2 to 01 a4. This is doubled. However, now the car tries to stall when I decelerate after normal acceleration and also does not hit max boost. I have reset my AVCR to relearn and that did not help. My next move is to adjust the K-Value +/- 5% to sse if it helps. Am I going in the right direction or do I need to make changes in the fuel map, as well? I have a copy of the BIN if anyone can assist. Thanks much...

I think the doolz requires a 70% alteration to the K not 100% which means you're really on the rich side of tuning.

I could be wrong though, after all my memory is not what it used to be Smile

That definitely helped on the low end and mid. Car pulls extremely hard, but still only hits .94 bar. My car would hit 1.25 bar with the single setup. The stalling issue has been fixed, however. Any other tips on the max boost problem? I have also reset the AVC-R and it did not help...

You may still be a bit rich. Check it out with a wide band O2 meter or on a dyno. A $50 check on dyno is cheaper than a new motor.
